The list looks pretty solid. Keep your two small Termagants squads in/behind cover and out of LoS! That size will be easy for your opponent to knock them out/off of an objective. The size of the Tervigon spawning will not be large either, so use cautious tactics! You could drop Ymgarl GS to 8 strong which is really efficient in my experience.
Also, backseat moderating again, but it is not necessary to list standard wargear/biomorphs/stats/special abilities, etc, etc. This is a borderline violation of forum rules and copyrights! It is only necessary to list chosen options/upgrades. Everyone who has the codex will know what they have and what they can do, so no need to list it out. Again, friendly and kind reminder.
